4.  The applicants were born in 1923, 1959 and 1963, respectively, and live in Casteltermini.
5.  The applicants are the joint owners of a plot of land designated as agricultural land in Casteltermini. The land in issue was recorded in the land register as Folio no. 40, Parcel no. 185.
6.  On 13 July 1989 the regional councillor for public works issued a decree authorising the Municipality to take possession, through an expedited procedure and on the basis of a public-interest declaration, of a portion of the applicants’ land in order to begin the construction of a road.
7.  On 4 January 1991 the authorities took physical possession of the land.
8.  By a writ served on 23 June 1998, the applicants brought an action for damages against the Casteltermini Municipality before the Agrigento District Court. They alleged that the occupation of the land was illegal and that the construction work had been completed without there having been a formal expropriation of the land and payment of compensation. They claimed a sum corresponding to the market value of the land and a further sum in damages for the loss of enjoyment of the land during the period of lawful occupation.
9.  On an unspecified date the court ordered an expert valuation of the land. In a report submitted on 17 September 2001 the expert concluded that the occupied land covered a surface area of 124.87 square metres and confirmed that it could be classified as building land. He further concluded that the market value of the land on the date the occupation became unlawful, which he identified as having occurred on 13 July 1994, corresponded to 6.20 euros (EUR) per square metre, for a total of EUR 773.88.
10.  By a judgment delivered on 22 January 2003 and filed with the court registry on 23 January 2003, the Agrigento District Court declared that the possession of the land, which had been initially authorised, had become unlawful as of 4 June 1993. It found that the land had been irreversibly transformed by the public works. As a result, in accordance with the constructive-expropriation rule (occupazione acquisitiva or accessione invertita), the applicants had been deprived of their property, by virtue of its irreversible alteration, on the date on which the possession had ceased to be lawful. In the light of those considerations, the court concluded that the applicants were entitled to compensation in consideration for the loss of ownership caused by the unlawful occupation.
11.  The court drew on the expert valuation to conclude that the land could be classified as agricultural land and that its market value on the date the occupation had become unlawful corresponded to EUR 773.88. However, in contrast with the expert’s finding, the court reiterated that the occupation had become unlawful as of 4 June 1993.
12.  Therefore, the court held that the applicants were entitled to compensation in the sum of EUR 773.88, to be adjusted for inflation, plus statutory interest.
13.  The court further awarded the applicants EUR 37.43 as compensation for the damage occasioned by the unavailability of the land during the period from the beginning of the lawful occupation (13 July 1989) until the date of loss of ownership (4 June 1993).
14.  The judgment became final in March 2004.
